Cobos started playing professionally with hometown club RC Strasbourg, helping it return to Ligue 1 in 1992 – he had already played in the top flight in the 1988–89 season, his official debut coming on 30 July 1988, in a 0–1 loss at Montpellier HSC.
Afterwards, Cobos spent three 1/2 years with Paris Saint-Germain FC, helping with 14 matches as the capital outfit won the league, and being a more important first-team unit in the next year, as it conquered the domestic cup; additionally, in the latter, he played in all the matches as the club reached the last-four in the UEFA Champions League.
Late into 1996, Cobos moved to the land of his ancestors, signing with Spain's RCD Espanyol, and being a first-team regular during his stay. Aged 30, he returned to his country, playing one year with Toulouse FC, then moving to OGC Nice, which he helped promote to level one in his third season, aged 34, appearing in 10 matches – ironically, he would appear significantly more in the following three seasons, with the Côte d'Azur side always maintaining its division status.
After retiring, with French first division totals of 235 games and 13 goals (plus 165 and five in the second level), Cobos continued to work with his last club, serving a two-year spell as assistant coach. In January 2009, two years after leaving Nice, he joined AS Monaco FC as its director of football, but only lasted three months in office.
Cobos' older brother, Vincent, was also a footballer and a defender. He too played mainly for Strasbourg (nine professional seasons), and the siblings shared teams from 1988–91.
